Systems and methods for conversations with devices about media using interruptions and changes of subjects

ABSTRACT

Systems and methods are described herein for providing media guidance. Control circuitry may receive a first voice input and access a database of topics to identify a first topic associated with the first voice input. A user interface may generate a first response to the first voice input, and subsequent to generating the first response, the control circuitry may receive a second voice input. The control circuitry may determine a match between the second voice input and an interruption input such as a period of silence or a keyword or a phrase, such as “Ahh,”, “Umm,”, or “Hmm.” The user interface may generate a second response that is associated with a second topic related to the first topic. By interrupting the conversation and changing the subject from time to time, media guidance systems can appear to be more intelligent and human.

BACKGROUND

Media guidance systems may include a voice interactive feature by whicha user can provide voice commands and queries to the media guidancesystem. The media guidance system may respond, through either text or amachine-generated voice, with a related answer or topic. For instance, auser may request recommendations for popular action movies, and themedia guidance system may access a database (such as the Apple Store orGoogle Play store), download a list of the top ten action movies, andprovide the list to the user. The media guidance system may furtherimprove the relevance of its responses by referencing a Knowledge Graph,which includes a semantic network that maintains relationships betweencertain topics and/or ideas.

In this manner, traditional media guidance systems have employed a“turn-based” approach, wherein a user and the media guidance system taketurns providing queries and answers. However, such a turn-based approachcan sometimes appear to be rigid or robotic.

SUMMARY

Accordingly, systems and methods for conversations with devices aboutmedia using interruption and changes of subjects are described herein. Amedia guidance application may interact with a user through a voiceinterface in an interactive conversation, wherein the user speaks avoice command and the media guidance application response with a spokenresponse. The media guidance application may, among other things,provide media guidance and recommendations to the user through the voiceinterface. For example, a user may state, “Rachael, what should I watchtonight?” The media guidance application may reply with “I think youshould try the new Bond movie.” The media guidance application may alsodetect when the user hesitates and interrupts or changes the subject.For example, continuing with the previous example, the user may say “hmm. . . ”, indicating some hesitation with the media guidanceapplication's recommendation of a Bond movie. The media guidanceapplication, detecting this hesitation, may interrupt and change thesubject, stating “How about Mission Impossible 3?” By interrupting theconversation and changing the subject from time to time, media guidancesystems can appear to be more intelligent and human.

According to one aspect, systems and methods are described herein forproviding media guidance. According to one aspect, control circuitry mayreceive a first voice input. The control circuitry may access a databaseof topics, the database of topics including a semantic networkindicating relationships between a plurality of topics and identify afirst topic from the database of topics that is associated with thefirst voice input. For example, the database of topics may be aKnowledge Graph that maintains relationships between topics/ideas.Knowledge graphs and their features are described in greater detail inU.S. patent application Ser. No. 14/501,504, filed Sep. 30, 2014, U.S.patent application Ser. No. 14/500,309, filed Sep. 29, 2014, and U.S.patent application Ser. No. 14/448,308, filed Jul. 31, 2014, which arehereby incorporated by reference herein in their entireties.

A user interface may generate a first response to the first voice input,and subsequent to generating the first response, the control circuitrymay receive a second voice input. The control circuitry may compare thesecond voice input to a list of interruption inputs to determine a matchbetween the second voice input and an interruption input from the listof interruption inputs. Interruption inputs may include, for example, aperiod of silence or a keyword or a phrase, such as “Ahh,”, “Umm,”,“Hmm,” or the like. In response to determining the match between thesecond voice input and the interruption input, the user interface maygenerate a second response to the first voice input, wherein the secondresponse is associated with a second topic from the database of topicsthat is associated with the first topic.

In some embodiments, the control circuitry may also extract, from thedatabase, relationships between the first topic and a reminder of theplurality of topics in order to select the second topic. The controlcircuitry may compare each of the relationships between the first topicand the remainder of the plurality of topics to a relationship thresholdand store to memory a list indicating a subset of the relationshipsbetween the first topic and the remainder of the plurality of topicsthat do not exceed the relationship threshold and a list of topics ofthe plurality of topics that correspond to the subset of therelationships. The second topic may then be selected from the list oftopics. In this manner, the second topic may be chosen so that it isrelated to the topic of the user's original query.

In some embodiments, the semantic network includes numericalrelationships between the plurality of topics, the numericalrelationships indicating a statistical likelihood that the second topicis related to the first topic. For example, the statistical likelihoodmay be determined by monitoring a plurality of voice inputs from aplurality of users. Of the plurality of voice inputs, a first subsetcould be identified that relate to a first topic, and of the firstsubset, a smaller second subset can be identified that relates to thesecond topic. From the first and the second subset, a probability thatthe second topic follows the first topic may be determined and may formthe basis of the statistical likelihood and/or relationship between thefirst topic and the second topic. Other methods of determining andmaintaining relationships in a database, semantic network, and/orKnowledge Graph are contemplated, as will be understood by those ofordinary skill in the art.

The second response may further take into account a user's mediapreferences. For example, the control circuitry may access a userprofile indicating media preferences of a user. A genre preference maybe retrieved from the user profile, and the control circuitry mayidentify a subset of the plurality of topics that are associated withthe retrieved genre. The second topic may then be selected from thesubset of the plurality of topics. Other methods of selecting the secondtopic may be contemplated. For instance, the user profile, as discussedherein, may include other information about the user's mediapreferences, including, but not limited to, ratings information,favorite actor information, preferred media format (e.g., standarddefinition, high definition, 3D, etc.), and preferred media category,among others. In some embodiments, the database of topics may indicate,for each of the plurality of topics, a genre associated with eachrespective topic. The control circuitry may extract, from the databaseof topics, a genre associated with the first topic and identify a subsetof the plurality of topics that are associated with the extracted genre.The second topic may then be selected from the subset of the pluralityof topics.

In some embodiments, it may not be desirable to interrupt or change thesubject of a conversation with high frequency. For instance, some usersmay prefer little or no interruptions when interacting with the mediaguidance system. In some embodiments, the control circuitry may receivea third voice input and compare the third voice input to the list ofinterruption inputs to determine a match between the third voice inputand a second interruption input from the list of interruption inputs.The control circuitry may determine whether an interruption thresholdperiod of time has elapsed between a current time and the secondresponse. In some embodiments, the interruption threshold period of timemay be specified by the user and may be a minimum period of time thatthe media guidance system must wait before interrupting or changing thesubject. In some embodiments, the interruption threshold period of timemay represent an average time between interruptions, such that the mediaguidance system is allowed flexibility to interrupt the user at anytime, as long as, on average, the time between interruptions does notfall below the average time. The control circuitry may, in response todetermining that the interruption threshold period of time has elapsedbetween the current time and the second response, generate a thirdresponse to the first voice input, wherein the third response isassociated with a third topic from the database of topics that isassociated with the first topic.

In some embodiments, a voice personality profile may store certain userpreferences regarding, among others, how often a media guidanceapplication may interrupt or change the subject of a conversation andhow far the media guidance application may deviate from a current topic.The control circuitry may receive an indication of a user associatedwith the first voice input. The control circuitry may then access aplurality of voice personality profiles, each voice personality profilecorresponding to a respective user and including indications of aplurality of interruption inputs and select one of the plurality ofvoice personality profiles based on the indication of the userassociated with the first voice input. In order to identify aninterruption input in the second voice input, the control circuitry maycompare the second voice input to the list of interruption inputs fromthe selected voice personality profile. For example, one user may oftenuse “Ahh . . . ” when pausing, while another user may often use “Hmm . .. ” when pausing, and the media guidance application may maintaindifferent voice personality profiles for each of these users. In someembodiments, the voice personality profiles may output responses indifferent voices. For example, one voice personality profile may soundlike a man when responding to a user, while another voice personalityprofile may sound like a woman.

In some embodiments, the control circuitry may limit the frequency ornumber of times the control circuitry interrupts the conversation basedon an interruption threshold period of time. The control circuitry mayextract the interruption threshold period of time from a voicepersonality profile. The control circuitry may calculate a time elapsedsince the first voice input by comparing a current time to a timeassociated with the first voice input. The control circuitry may onlygenerate the second response in this embodiment if the time elapsed hasexceeded the interruption threshold period of time.

As an illustrative example, a user may invoke the media guidanceapplication and say “Rachael, suggest a video, please.” The user'sreference to “Rachael” may cause the guidance system to load a specificartificial personality called “Rachael.” This personality may use aspecific female voice to interact with the user and may also indicate(1) an interruption threshold period of time that controls howfrequently to interrupt the conversation; and (2) a relationshipthreshold that indicates how far “Rachael” is allowed to move away fromthe current subject when interrupting or changing the subject.

Rachael may reply, “You were one hour and eighteen minutes into NOVA's‘Becoming Human—Part 1.’ Would you like to watch the rest of thisprogram?” The user may respond with, “Ah . . . ” The media guidancesystem may detect the word “Ah” as an interruption input and determinethat it is a suitable time to interrupt. Rachael, interrupting theconversation, may then state “Alternatively, the Smithsonian Channel hasa similar program called ‘Smithsonian Spotlight: Human Origins.’ Howabout this program?” The media guidance application may have accessed aKnowledge Graph to determine that the Smithsonian program is related tothe NOVA program. The user may respond to the recommendation of theSmithsonian program with two seconds of silence. The media guidanceapplication may identify the silence as another interruption point.However, this time, Rachael may respond with: “How about somethingcompletely different?” indicating whether the media guidance system maysuggest a topic which exceeds the relationship threshold. In thismanner, the media guidance application may, in some embodiments, querythe user for permission to exceed the relationship threshold after oneor more unsuccessful recommendations.

It should be noted that the systems and/or methods described above maybe applied to, or used in accordance with, other systems, methods and/orapparatuses.

DETAILED DESCRIPTION OF THE DRAWINGS

Systems and methods for conversations with devices about media usinginterruption and changes of subjects are described herein. A mediaguidance application may interact with a user through a voice interfacein an interactive conversation, wherein the user speaks a voice commandand the media guidance application response with a spoken response. Themedia guidance application may, among other things, provide mediaguidance and recommendations to the user through the voice interface.The media guidance application may also detect when the user hesitatesand interrupts or changes the subject at that point. The media guidancemay change the subject to a topic that is related to the user's originalquery to provide more relevant answers to the user.

The amount of content available to users in any given content deliverysystem can be substantial. Consequently, many users desire a form ofmedia guidance through an interface that allows users to efficientlynavigate content selections and easily identify content that they maydesire. An application that provides such guidance is referred to hereinas an interactive media guidance application or, sometimes, a mediaguidance application or a guidance application.

Interactive media guidance applications may take various forms dependingon the content for which they provide guidance. One typical type ofmedia guidance application is an interactive television program guide.Interactive television program guides (sometimes referred to aselectronic program guides) are well-known guidance applications that,among other things, allow users to navigate among and locate many typesof content or media assets. Interactive media guidance applications maygenerate graphical user interface screens that enable a user to navigateamong, locate and select content. As referred to herein, the terms“media asset” and “content” should be understood to mean anelectronically consumable user asset, such as television programming, aswell as pay-per-view programs, on-demand programs (as in video-on-demand(VOD) systems), Internet content (e.g., streaming content, downloadablecontent, Webcasts, etc.), video clips, audio, content information,pictures, rotating images, documents, playlists, websites, articles,books, electronic books, blogs, advertisements, chat sessions, socialmedia, applications, games, and/or any other media or multimedia and/orcombination of the same. Guidance applications also allow users tonavigate among and locate content. As referred to herein, the term“multimedia” should be understood to mean content that utilizes at leasttwo different content forms described above, for example, text, audio,images, video, or interactivity content forms. Content may be recorded,played, displayed or accessed by user equipment devices, but can also bepart of a live performance.

The media guidance application and/or any instructions for performingany of the embodiments discussed herein may be encoded on computerreadable media. Computer readable media includes any media capable ofstoring data. The computer readable media may be transitory, including,but not limited to, propagating electrical or electromagnetic signals,or may be non-transitory including, but not limited to, volatile andnon-volatile computer memory or storage devices such as a hard disk,floppy disk, USB drive, DVD, CD, media cards, register memory, processorcaches, Random Access Memory (“RAM”), etc.

With the advent of the Internet, mobile computing, and high-speedwireless networks, users are accessing media on user equipment deviceson which they traditionally did not. As referred to herein, the phrase“user equipment device,” “user equipment,” “user device,” “electronicdevice,” “electronic equipment,” “media equipment device,” or “mediadevice” should be understood to mean any device for accessing thecontent described above, such as a television, a Smart TV, a set-topbox, an integrated receiver decoder (IRD) for handling satellitetelevision, a digital storage device, a digital media receiver (DMR), adigital media adapter (DMA), a streaming media device, a DVD player, aDVD recorder, a connected DVD, a local media server, a BLU-RAY player, aBLU-RAY recorder, a personal computer (PC), a laptop computer, a tabletcomputer, a WebTV box, a personal computer television (PC/TV), a PCmedia server, a PC media center, a hand-held computer, a stationarytelephone, a personal digital assistant (PDA), a mobile telephone, aportable video player, a portable music player, a portable gamingmachine, a smart phone, or any other television equipment, computingequipment, or wireless device, and/or combination of the same. In someembodiments, the user equipment device may have a front facing screenand a rear facing screen, multiple front screens, or multiple angledscreens. In some embodiments, the user equipment device may have a frontfacing camera and/or a rear facing camera. On these user equipmentdevices, users may be able to navigate among and locate the same contentavailable through a television. Consequently, media guidance may beavailable on these devices, as well. The guidance provided may be forcontent available only through a television, for content available onlythrough one or more of other types of user equipment devices, or forcontent available both through a television and one or more of the othertypes of user equipment devices. The media guidance applications may beprovided as on-line applications (i.e., provided on a web-site), or asstand-alone applications or clients on user equipment devices. Variousdevices and platforms that may implement media guidance applications aredescribed in more detail below.

One of the functions of the media guidance application is to providemedia guidance data to users. As referred to herein, the phrase “mediaguidance data” or “guidance data” should be understood to mean any datarelated to content or data used in operating the guidance application.For example, the guidance data may include program information, guidanceapplication settings, user preferences, user profile information, medialistings, media-related information (e.g., broadcast times, broadcastchannels, titles, descriptions, ratings information (e.g., parentalcontrol ratings, critic's ratings, etc.), genre or category information,actor information, logo data for broadcasters' or providers' logos,etc.), media format (e.g., standard definition, high definition, 3D,etc.), advertisement information (e.g., text, images, media clips,etc.), on-demand information, blogs, websites, and any other type ofguidance data that is helpful for a user to navigate among and locatedesired content selections.

In some embodiments, the media guidance data may include a semanticnetwork that maintains relationships between topics, ideas, and/orconcepts. As will be understood by those of ordinary skill in the art, asemantic network or semantic graph may include a directed or undirectedgraph consisting of vertices, which represent topics, ideas, orconcepts, and edges which represent the relationships between theconcepts. In some embodiments, the semantic network may include aKnowledge Graph. The semantic network may be populated using anysuitable approach. For instance, in some embodiments, the relationshipsmay include numeric values indicating the similarity between differenttopics, ideas, or concepts.

The media guidance data may also include one or more voice personalityprofiles including at least a relationship threshold and an interruptionthreshold period of time. The relationship threshold may indicate a“distance” that a media guidance application may deviate from a currentsubject when interrupting or changing the subject. For example, inembodiments where a semantic network includes relationships includingnumeric values between the vertices, the relationship threshold may be amaximum value between a first topic and a second topic, so that themedia guidance application does not deviate beyond the relationshipthreshold when interrupting or changing the subject. The interruptionthreshold period of time may indicate a frequency with which the mediaguidance application may interrupt or change the subject of aconversation. In some embodiments, the interruption threshold period oftime may represent a minimum amount of time that must pass betweensubsequent interruptions of the conversation. In other embodiments, theinterruption threshold period of time may represent an average amount oftime between subsequent interruptions. Thus, in these embodiments, thetime between certain interruptions may be less than the interruptionthreshold period of time, so long as, on average, the time betweeninterruptions is kept at or above the interruption threshold period oftime.

FIGS. 1-2 show illustrative display screens that may be used to providemedia guidance data. The display screens shown in FIGS. 1-2 may beimplemented on any suitable user equipment device or platform. While thedisplays of FIGS. 1-2 are illustrated as full screen displays, they mayalso be fully or partially overlaid over content being displayed: A usermay indicate a desire to access content information by selecting aselectable option provided in a display screen (e.g., a menu option, alistings option, an icon, a hyperlink, etc.) or pressing a dedicatedbutton (e.g., a GUIDE button) on a remote control or other user inputinterface or device. In response to the user's indication, the mediaguidance application may provide a display screen with media guidancedata organized in one of several ways, such as by time and channel in agrid, by time, by channel, by source, by content type, by category(e.g., movies, sports, news, children, or other categories ofprogramming), or other predefined, user-defined, or other organizationcriteria.

FIG. 1 shows illustrative grid of a program listings display 100arranged by time and channel that also enables access to different typesof content in a single display. Display 100 may include grid 102 with:(1) a column of channel/content type identifiers 104, where eachchannel/content type identifier (which is a cell in the column)identifies a different channel or content type available; and (2) a rowof time identifiers 106, where each time identifier (which is a cell inthe row) identifies a time block of programming. Grid 102 also includescells of program listings, such as program listing 108, where eachlisting provides the title of the program provided on the listing'sassociated channel and time. With a user input device, a user can selectprogram listings by moving highlight region 110. Information relating tothe program listing selected by highlight region 110 may be provided inprogram information region 112. Region 112 may include, for example, theprogram title, the program description, the time the program is provided(if applicable), the channel the program is on (if applicable), theprogram's rating, and other desired information.

In addition to providing access to linear programming (e.g., contentthat is scheduled to be transmitted to a plurality of user equipmentdevices at a predetermined time and is provided according to aschedule), the media guidance application also provides access tonon-linear programming (e.g., content accessible to a user equipmentdevice at any time and is not provided according to a schedule).Non-linear programming may include content from different contentsources including on-demand content (e.g., VOD), Internet content (e.g.,streaming media, downloadable media, etc.), locally stored content(e.g., content stored on any user equipment device described above orother storage device), or other time-independent content. On-demandcontent may include movies or any other content provided by a particularcontent provider (e.g., HBO On Demand providing “The Sopranos” and “CurbYour Enthusiasm”). HBO ON DEMAND is a service mark owned by Time WarnerCompany L.P. et al. and THE SOPRANOS and CURB YOUR ENTHUSIASM aretrademarks owned by the Home Box Office, Inc. Internet content mayinclude web events, such as a chat session or Webcast, or contentavailable on-demand as streaming content or downloadable content throughan Internet web site or other Internet access (e.g. FTP).

Grid 102 may provide media guidance data for non-linear programmingincluding on-demand listing 114, recorded content listing 116, andInternet content listing 118. A display combining media guidance datafor content from different types of content sources is sometimesreferred to as a “mixed-media” display. Various permutations of thetypes of media guidance data that may be displayed that are differentthan display 100 may be based on user selection or guidance applicationdefinition (e.g., a display of only recorded and broadcast listings,only on-demand and broadcast listings, etc.). As illustrated, listings114, 116, and 118 are shown as spanning the entire time block displayedin grid 102 to indicate that selection of these listings may provideaccess to a display dedicated to on-demand listings, recorded listings,or Internet listings, respectively. In some embodiments, listings forthese content types may be included directly in grid 102. Additionalmedia guidance data may be displayed in response to the user selectingone of the navigational icons 120. (Pressing an arrow key on a userinput device may affect the display in a similar manner as selectingnavigational icons 120.)

Display 100 may also include video region 122, advertisement 124, andoptions region 126. Video region 122 may allow the user to view and/orpreview programs that are currently available, will be available, orwere available to the user. The content of video region 122 maycorrespond to, or be independent from, one of the listings displayed ingrid 102. Grid displays including a video region are sometimes referredto as picture-in-guide (PIG) displays. PIG displays and theirfunctionalities are described in greater detail in Satterfield et al.U.S. Pat. No. 6,564,378, issued May 13, 2003 and Yuen et al. U.S. Pat.No. 6,239,794, issued May 29, 2001, which are hereby incorporated byreference herein in their entireties. PIG displays may be included inother media guidance application display screens of the embodimentsdescribed herein.

Advertisement 124 may provide an advertisement for content that,depending on a viewer's access rights (e.g., for subscriptionprogramming), is currently available for viewing, will be available forviewing in the future, or may never become available for viewing, andmay correspond to or be unrelated to one or more of the content listingsin grid 102. Advertisement 124 may also be for products or servicesrelated or unrelated to the content displayed in grid 102. Advertisement124 may be selectable and provide further information about content,provide information about a product or a service, enable purchasing ofcontent, a product, or a service, provide content relating to theadvertisement, etc. Advertisement 124 may be targeted based on a user'sprofile/preferences, monitored user activity, the type of displayprovided, or on other suitable targeted advertisement bases.

While advertisement 124 is shown as rectangular or banner shaped,advertisements may be provided in any suitable size, shape, and locationin a guidance application display. For example, advertisement 124 may beprovided as a rectangular shape that is horizontally adjacent to grid102. This is sometimes referred to as a panel advertisement. Inaddition, advertisements may be overlaid over content or a guidanceapplication display or embedded within a display. Advertisements mayalso include text, images, rotating images, video clips, or other typesof content described above. Advertisements may be stored in a userequipment device having a guidance application, in a database connectedto the user equipment, in a remote location (including streaming mediaservers), or on other storage means, or a combination of theselocations. Providing advertisements in a media guidance application isdiscussed in greater detail in, for example, Knudson et al., U.S. PatentApplication Publication No. 2003/0110499, filed Jan. 17, 2003; Ward, IIIet al. U.S. Pat. No. 6,756,997, issued Jun. 29, 2004; and Schein et al.U.S. Pat. No. 6,388,714, issued May 14, 2002, which are herebyincorporated by reference herein in their entireties. It will beappreciated that advertisements may be included in other media guidanceapplication display screens of the embodiments described herein.

Options region 126 may allow the user to access different types ofcontent, media guidance application displays, and/or media guidanceapplication features. Options region 126 may be part of display 100 (andother display screens described herein), or may be invoked by a user byselecting an on-screen option or pressing a dedicated or assignablebutton on a user input device. The selectable options within optionsregion 126 may concern features related to program listings in grid 102or may include options available from a main menu display. Featuresrelated to program listings may include searching for other air times orways of receiving a program, recording a program, enabling seriesrecording of a program, setting program and/or channel as a favorite,purchasing a program, or other features. Options available from a mainmenu display may include search options, VOD options, parental controloptions, Internet options, cloud-based options, device synchronizationoptions, second screen device options, options to access various typesof media guidance data displays, options to subscribe to a premiumservice, options to edit a user's profile, options to access a browseoverlay, or other options. The options may also include the ability toselect one of a plurality of voice personality profiles, each voicepersonality profiles including at least an indication of a relationshipthreshold and an interruption threshold period of time. In someembodiments, the voice personality profile also includes a specificvoice for providing responses to the user as well as pointers to auser's preference profile. In this manner, a user may choose the“personality” of the media guidance application that he or she will beinteracting with, with each “personality” comprising parameters thatdetermine how often the personality may interrupt the user and how farthe personality may stray from a current topic when changing the subjectof a conversation.

The media guidance application may be personalized based on a user'spreferences. A personalized media guidance application allows a user tocustomize displays and features to create a personalized “experience”with the media guidance application. This personalized experience may becreated by allowing a user to input these customizations and/or by themedia guidance application monitoring user activity to determine varioususer preferences. Users may access their personalized guidanceapplication by logging in or otherwise identifying themselves to theguidance application. Customization of the media guidance applicationmay be made in accordance with a user profile. The customizations mayinclude varying presentation schemes (e.g., color scheme of displays,font size of text, etc.), aspects of content listings displayed (e.g.,only HDTV or only 3D programming, user-specified broadcast channelsbased on favorite channel selections, re-ordering the display ofchannels, recommended content, etc.), desired recording features (e.g.,recording or series recordings for particular users, recording quality,etc.), parental control settings, customized presentation of Internetcontent (e.g., presentation of social media content, e-mail,electronically delivered articles, etc.) and other desiredcustomizations.

The media guidance application may allow a user to provide user profileinformation or may automatically compile user profile information. Themedia guidance application may, for example, monitor the content theuser accesses and/or other interactions the user may have with theguidance application. Additionally, the media guidance application mayobtain all or part of other user profiles that are related to aparticular user (e.g., from other web sites on the Internet the useraccesses, such as www.allrovi.com, from other media guidanceapplications the user accesses, from other interactive applications theuser accesses, from another user equipment device of the user, etc.),and/or obtain information about the user from other sources that themedia guidance application may access. As a result, a user can beprovided with a unified guidance application experience across theuser's different user equipment devices. This type of user experience isdescribed in greater detail below in connection with FIG. 4. Additionalpersonalized media guidance application features are described ingreater detail in Ellis et al., U.S. Patent Application Publication No.2005/0251827, filed Jul. 11, 2005, Boyer et al., U.S. Pat. No.7,165,098, issued Jan. 16, 2007, and Ellis et al., U.S. PatentApplication Publication No. 2002/0174430, filed Feb. 21, 2002, which arehereby incorporated by reference herein in their entireties.

Another display arrangement for providing media guidance is shown inFIG. 2. Video mosaic display 200 includes selectable options 202 forcontent information organized based on content type, genre, and/or otherorganization criteria. In display 200, television listings option 204 isselected, thus providing listings 206, 208, 210, and 212 as broadcastprogram listings. In display 200 the listings may provide graphicalimages including cover art, still images from the content, video clippreviews, live video from the content, or other types of content thatindicate to a user the content being described by the media guidancedata in the listing. Each of the graphical listings may also beaccompanied by text to provide further information about the contentassociated with the listing. For example, listing 208 may include morethan one portion, including media portion 214 and text portion 216.Media portion 214 and/or text portion 216 may be selectable to viewcontent in full-screen or to view information related to the contentdisplayed in media portion 214 (e.g., to view listings for the channelthat the video is displayed on).

The listings in display 200 are of different sizes (i.e., listing 206 islarger than listings 208, 210, and 212), but if desired, all thelistings may be the same size. Listings may be of different sizes orgraphically accentuated to indicate degrees of interest to the user orto emphasize certain content, as desired by the content provider orbased on user preferences.

Various systems and methods for graphically accentuating contentlistings are discussed in, for example, Yates, U.S. Patent ApplicationPublication No. 2010/0153885, filed Dec. 29, 2005, which is herebyincorporated by reference herein in its entirety.

Users may access content and the media guidance application (and itsdisplay screens described above and below) from one or more of theiruser equipment devices. FIG. 3 shows a generalized embodiment ofillustrative user equipment device 300. More specific implementations ofuser equipment devices are discussed below in connection with FIG. 4.User equipment device 300 may receive content and data via input/output(hereinafter “I/O”) path 302. I/O path 302 may provide content (e.g.,broadcast programming, on-demand programming, Internet content, contentavailable over a local area network (LAN) or wide area network (WAN),and/or other content) and data to control circuitry 304, which includesprocessing circuitry 306 and storage 308. Control circuitry 304 may beused to send and receive commands, requests, and other suitable datausing I/O path 302. I/O path 302 may connect control circuitry 304 (andspecifically processing circuitry 306) to one or more communicationspaths (described below). I/O functions may be provided by one or more ofthese communications paths, but are shown as a single path in FIG. 3 toavoid overcomplicating the drawing.

Control circuitry 304 may be based on any suitable processing circuitrysuch as processing circuitry 306. As referred to herein, processingcircuitry should be understood to mean circuitry based on one or moremicroprocessors, microcontrollers, digital signal processors,programmable logic devices, field-programmable gate arrays (FPGAs),application-specific integrated circuits (ASICs), etc., and may includea multi-core processor (e.g., dual-core, quad-core, hexa-core, or anysuitable number of cores) or supercomputer. In some embodiments,processing circuitry may be distributed across multiple separateprocessors or processing units, for example, multiple of the same typeof processing units (e.g., two Intel Core i7 processors) or multipledifferent processors (e.g., an Intel Core i5 processor and an Intel Corei7 processor). In some embodiments, control circuitry 304 executesinstructions for a media guidance application stored in memory (i.e.,storage 308). Specifically, control circuitry 304 may be instructed bythe media guidance application to perform the functions discussed aboveand below. For example, the media guidance application may provideinstructions to control circuitry 304 to generate the media guidancedisplays. In some implementations, any action performed by controlcircuitry 304 may be based on instructions received from the mediaguidance application.

In client-server based embodiments, control circuitry 304 may includecommunications circuitry suitable for communicating with a guidanceapplication server or other networks or servers. The instructions forcarrying out the above mentioned functionality may be stored on theguidance application server. Communications circuitry may include acable modem, an integrated services digital network (ISDN) modem, adigital subscriber line (DSL) modem, a telephone modem, Ethernet card,or a wireless modem for communications with other equipment, or anyother suitable communications circuitry. Such communications may involvethe Internet or any other suitable communications networks or paths(which is described in more detail in connection with FIG. 4). Inaddition, communications circuitry may include circuitry that enablespeer-to-peer communication of user equipment devices, or communicationof user equipment devices in locations remote from each other (describedin more detail below).

Memory may be an electronic storage device provided as storage 308 thatis part of control circuitry 304. As referred to herein, the phrase“electronic storage device” or “storage device” should be understood tomean any device for storing electronic data, computer software, orfirmware, such as random-access memory, read-only memory, hard drives,optical drives, digital video disc (DVD) recorders, compact disc (CD)recorders, BLU-RAY disc (BD) recorders, BLU-RAY 3D disc recorders,digital video recorders (DVR, sometimes called a personal videorecorder, or PVR), solid state devices, quantum storage devices, gamingconsoles, gaming media, or any other suitable fixed or removable storagedevices, and/or any combination of the same. Storage 308 may be used tostore various types of content described herein as well as mediaguidance data described above. Nonvolatile memory may also be used(e.g., to launch a boot-up routine and other instructions). Cloud-basedstorage, described in relation to FIG. 4, may be used to supplementstorage 308 or instead of storage 308.

Control circuitry 304 may include video generating circuitry and tuningcircuitry, such as one or more analog tuners, one or more MPEG-2decoders or other digital decoding circuitry, high-definition tuners, orany other suitable tuning or video circuits or combinations of suchcircuits. Encoding circuitry (e.g., for converting over-the-air, analog,or digital signals to MPEG signals for storage) may also be provided.Control circuitry 304 may also include scaler circuitry for upconvertingand downconverting content into the preferred output format of the userequipment 300. Circuitry 304 may also include digital-to-analogconverter circuitry and analog-to-digital converter circuitry forconverting between digital and analog signals. The tuning and encodingcircuitry may be used by the user equipment device to receive and todisplay, to play, or to record content. The tuning and encodingcircuitry may also be used to receive guidance data. The circuitrydescribed herein, including for example, the tuning, video generating,encoding, decoding, encrypting, decrypting, scaler, and analog/digitalcircuitry, may be implemented using software running on one or moregeneral purpose or specialized processors. Multiple tuners may beprovided to handle simultaneous tuning functions (e.g., watch and recordfunctions, picture-in-picture (PIP) functions, multiple-tuner recording,etc.). If storage 308 is provided as a separate device from userequipment 300, the tuning and encoding circuitry (including multipletuners) may be associated with storage 308.

The control circuitry 304 may also include audio comparison circuitrysuitable for recognizing voice inputs by a user, converting the voiceinput into text, and comparing the voice input to a database ofinterruption inputs. For example, the control circuitry 304 may includededicated hardware to perform audio processing algorithms and/or audiorecognition and comparison software. The control circuitry 304 mayaccess and run audio processing software stored on storage, such asstorage 308.

A user may send instructions to control circuitry 304 using user inputinterface 310. User input interface 310 may be any suitable userinterface, such as a remote control, mouse, trackball, keypad, keyboard,touch screen, touchpad, stylus input, joystick, voice recognitioninterface, or other user input interfaces. Display 312 may be providedas a stand-alone device or integrated with other elements of userequipment device 300. For example, display 312 may be a touchscreen ortouch-sensitive display. In such circumstances, user input interface 310may be integrated with or combined with display 312. Display 312 may beone or more of a monitor, a television, a liquid crystal display (LCD)for a mobile device, amorphous silicon display, low temperature polysilicon display, electronic ink display, electrophoretic display, activematrix display, electro-wetting display, electrofluidic display, cathoderay tube display, light-emitting diode display, electroluminescentdisplay, plasma display panel, high-performance addressing display,thin-film transistor display, organic light-emitting diode display,surface-conduction electron-emitter display (SED), laser television,carbon nanotubes, quantum dot display, interferometric modulatordisplay, or any other suitable equipment for displaying visual images.In some embodiments, display 312 may be HDTV-capable. In someembodiments, display 312 may be a 3D display, and the interactive mediaguidance application and any suitable content may be displayed in 3D. Avideo card or graphics card may generate the output to the display 312.The video card may offer various functions such as accelerated renderingof 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or theability to connect multiple monitors. The video card may be anyprocessing circuitry described above in relation to control circuitry304. The video card may be integrated with the control circuitry 304.Speakers 314 may be provided as integrated with other elements of userequipment device 300 or may be stand-alone units. The audio component ofvideos and other content displayed on display 312 may be played throughspeakers 314. In some embodiments, the audio may be distributed to areceiver (not shown), which processes and outputs the audio via speakers314.

The guidance application may be implemented using any suitablearchitecture. For example, it may be a stand-alone applicationwholly-implemented on user equipment device 300. In such an approach,instructions of the application are stored locally (e.g., in storage308), and data for use by the application is downloaded on a periodicbasis (e.g., from an out-of-band feed, from an Internet resource, orusing another suitable approach). Control circuitry 304 may retrieveinstructions of the application from storage 308 and process theinstructions to generate any of the displays discussed herein. Based onthe processed instructions, control circuitry 304 may determine whataction to perform when input is received from input interface 310. Forexample, movement of a cursor on a display up/down may be indicated bythe processed instructions when input interface 310 indicates that anup/down button was selected.

Detection module 316, or the detection module circuitry, may beincorporated into, coupled to, or accessible by the media guidanceapplication (such as control circuitry 304). Detection module 316 may beused, among other things, to detect user voice inputs. For example thedetection module 316 may capture audio signals and identify when a useris speaking to the media guidance application. In some embodiments, thedetection module 316 may establish a baseline signal, such as a periodof silence or background noise, by monitoring an audio signal before theuser input. The detection module 316 may detect the user voice input bydetecting that the audio signal deviates past a threshold value betweena start and an end time. In some embodiments, the media guidanceapplication may distinguish between whether the user is speakingspecifically to the media guidance application or to someone else. Forexample, the media guidance application may employ the use of keywords,such as a name of the media guidance application, that acts as a triggerfor the detection module 316 to begin listening for a user voice input.In such embodiments, the media guidance application may run, in realtime, audio recognition software that can detect spoken words in amonitored audio signal. In response to detecting the keyword, the mediaguidance application may start detecting a user voice input. The mediaguidance application may determine the end of the user voice input bydetecting a period of silence or by detecting a different keyword.

In some embodiments, the media guidance application is a client-serverbased application. Data for use by a thick or thin client implemented onuser equipment device 300 is retrieved on-demand by issuing requests toa server remote to the user equipment device 300. In one example of aclient-server based guidance application, control circuitry 304 runs aweb browser that interprets web pages provided by a remote server. Forexample, the remote server may store the instructions for theapplication in a storage device. The remote server may process thestored instructions using circuitry (e.g., control circuitry 304) andgenerate the displays discussed above and below. The client device mayreceive the displays generated by the remote server and may display thecontent of the displays locally on equipment device 300. This way, theprocessing of the instructions is performed remotely by the server whilethe resulting displays are provided locally on equipment device 300.Equipment device 300 may receive inputs from the user via inputinterface 310 and transmit those inputs to the remote server forprocessing and generating the corresponding displays. For example,equipment device 300 may transmit a communication to the remote serverindicating that an up/down button was selected via input interface 310.The remote server may process instructions in accordance with that inputand generate a display of the application corresponding to the input(e.g., a display that moves a cursor up/down). The generated display isthen transmitted to equipment device 300 for presentation to the user.

In some embodiments, the media guidance application is downloaded andinterpreted or otherwise run by an interpreter or virtual machine (runby control circuitry 304). In some embodiments, the guidance applicationmay be encoded in the ETV Binary Interchange Format (EBIF), received bycontrol circuitry 304 as part of a suitable feed, and interpreted by auser agent running on control circuitry 304. For example, the guidanceapplication may be an EBIF application. In some embodiments, theguidance application may be defined by a series of JAVA-based files thatare received and run by a local virtual machine or other suitablemiddleware executed by control circuitry 304. In some of suchembodiments (e.g., those employing MPEG-2 or other digital mediaencoding schemes), the guidance application may be, for example, encodedand transmitted in an MPEG-2 object carousel with the MPEG audio andvideo packets of a program.

User equipment device 300 of FIG. 3 can be implemented in system 400 ofFIG. 4 as user television equipment 402, user computer equipment 404,wireless user communications device 406, or any other type of userequipment suitable for accessing content, such as a non-portable gamingmachine. For simplicity, these devices may be referred to hereincollectively as user equipment or user equipment devices, and may besubstantially similar to user equipment devices described above. Userequipment devices, on which a media guidance application may beimplemented, may function as a standalone device or may be part of anetwork of devices. Various network configurations of devices may beimplemented and are discussed in more detail below.

A user equipment device utilizing at least some of the system featuresdescribed above in connection with FIG. 3 may not be classified solelyas user television equipment 402, user computer equipment 404, or awireless user communications device 406. For example, user televisionequipment 402 may, like some user computer equipment 404, beInternet-enabled allowing for access to Internet content, while usercomputer equipment 404 may, like some television equipment 402, includea tuner allowing for access to television programming. The mediaguidance application may have the same layout on various different typesof user equipment or may be tailored to the display capabilities of theuser equipment. For example, on user computer equipment 404, theguidance application may be provided as a web site accessed by a webbrowser. In another example, the guidance application may be scaled downfor wireless user communications devices 406.

In system 400, there is typically more than one of each type of userequipment device but only one of each is shown in FIG. 4 to avoidovercomplicating the drawing. In addition, each user may utilize morethan one type of user equipment device and also more than one of eachtype of user equipment device.

In some embodiments, a user equipment device (e.g., user televisionequipment 402, user computer equipment 404, wireless user communicationsdevice 406) may be referred to as a “second screen device.” For example,a second screen device may supplement content presented on a first userequipment device. The content presented on the second screen device maybe any suitable content that supplements the content presented on thefirst device. In some embodiments, the second screen device provides aninterface for adjusting settings and display preferences of the firstdevice. In some embodiments, the second screen device is configured forinteracting with other second screen devices or for interacting with asocial network. The second screen device can be located in the same roomas the first device, a different room from the first device but in thesame house or building, or in a different building from the firstdevice.

The user may also set various settings to maintain consistent mediaguidance application settings across in-home devices and remote devices.Settings include those described herein, as well as channel and programfavorites, programming preferences that the guidance applicationutilizes to make programming recommendations, display preferences, andother desirable guidance settings. For example, if a user sets a channelas a favorite on, for example, the web site www.allrovi.com on theirpersonal computer at their office, the same channel would appear as afavorite on the user's in-home devices (e.g., user television equipmentand user computer equipment) as well as the user's mobile devices, ifdesired. Therefore, changes made on one user equipment device can changethe guidance experience on another user equipment device, regardless ofwhether they are the same or a different type of user equipment device.In addition, the changes made may be based on settings input by a user,as well as user activity monitored by the guidance application.

The user equipment devices may be coupled to communications network 414.Namely, user television equipment 402, user computer equipment 404, andwireless user communications device 406 are coupled to communicationsnetwork 414 via communications paths 408, 410, and 412, respectively.Communications network 414 may be one or more networks including theInternet, a mobile phone network, mobile voice or data network (e.g., a4G or LTE network), cable network, public switched telephone network, orother types of communications network or combinations of communicationsnetworks. Paths 408, 410, and 412 may separately or together include oneor more communications paths, such as, a satellite path, a fiber-opticpath, a cable path, a path that supports Internet communications (e.g.,IPTV), free-space connections (e.g., for broadcast or other wirelesssignals), or any other suitable wired or wireless communications path orcombination of such paths. Path 412 is drawn with dotted lines toindicate that in the exemplary embodiment shown in FIG. 4 it is awireless path and paths 408 and 410 are drawn as solid lines to indicatethey are wired paths (although these paths may be wireless paths, ifdesired). Communications with the user equipment devices may be providedby one or more of these communications paths, but are shown as a singlepath in FIG. 4 to avoid overcomplicating the drawing.

Although communications paths are not drawn between user equipmentdevices, these devices may communicate directly with each other viacommunication paths, such as those described above in connection withpaths 408, 410, and 412, as well as other short-range point-to-pointcommunication paths, such as USB cables, IEEE 1394 cables, wirelesspaths (e.g., Bluetooth, infrared, IEEE 802-11x, etc.), or othershort-range communication via wired or wireless paths. BLUETOOTH is acertification mark owned by Bluetooth SIG, INC. The user equipmentdevices may also communicate with each other directly through anindirect path via communications network 414.

System 400 includes content source 416 and media guidance data source418 coupled to communications network 414 via communication paths 420and 422, respectively. Paths 420 and 422 may include any of thecommunication paths described above in connection with paths 408, 410,and 412. Communications with the content source 416 and media guidancedata source 418 may be exchanged over one or more communications paths,but are shown as a single path in FIG. 4 to avoid overcomplicating thedrawing. In addition, there may be more than one of each of contentsource 416 and media guidance data source 418, but only one of each isshown in FIG. 4 to avoid overcomplicating the drawing. (The differenttypes of each of these sources are discussed below.) If desired, contentsource 416 and media guidance data source 418 may be integrated as onesource device. Although communications between sources 416 and 418 withuser equipment devices 402, 404, and 406 are shown as throughcommunications network 414, in some embodiments, sources 416 and 418 maycommunicate directly with user equipment devices 402, 404, and 406 viacommunication paths (not shown) such as those described above inconnection with paths 408, 410, and 412.

Content source 416 may include one or more types of content distributionequipment including a television distribution facility, cable systemheadend, satellite distribution facility, programming sources (e.g.,television broadcasters, such as NBC, ABC, HBO, etc.), intermediatedistribution facilities and/or servers, Internet providers, on-demandmedia servers, and other content providers. NBC is a trademark owned bythe National Broadcasting Company, Inc., ABC is a trademark owned by theAmerican Broadcasting Company, Inc., and HBO is a trademark owned by theHome Box Office, Inc. Content source 416 may be the originator ofcontent (e.g., a television broadcaster, a Webcast provider, etc.) ormay not be the originator of content (e.g., an on-demand contentprovider, an Internet provider of content of broadcast programs fordownloading, etc.). Content source 416 may include cable sources,satellite providers, on-demand providers, Internet providers,over-the-top content providers, or other providers of content. Contentsource 416 may also include a remote media server used to storedifferent types of content (including video content selected by a user),in a location remote from any of the user equipment devices. Systems andmethods for remote storage of content, and providing remotely storedcontent to user equipment are discussed in greater detail in connectionwith Ellis et al., U.S. Pat. No. 7,761,892, issued Jul. 20, 2010, whichis hereby incorporated by reference herein in its entirety.

Media guidance data source 418 may provide media guidance data, such asthe media guidance data described above. Media guidance data may beprovided to the user equipment devices using any suitable approach. Insome embodiments, the guidance application may be a stand-aloneinteractive television program guide that receives program guide datavia a data feed (e.g., a continuous feed or trickle feed). Programschedule data and other guidance data may be provided to the userequipment on a television channel sideband, using an in-band digitalsignal, using an out-of-band digital signal, or by any other suitabledata transmission technique. Program schedule data and other mediaguidance data may be provided to user equipment on multiple analog ordigital television channels.

In some embodiments, media guidance data source 418 may store a databaseof topics including a semantic network. Upon request, media guidancedata source 418 may access the database and transmit a list of topics ora subset of topics related to a first topic. Media guidance data source418 may also search the database of topics for topics related to thefirst topic.

Media guidance data source 418 may also include a list of potentialinterruption inputs. For example, an interruption input may include aperiod of silence for a particular amount of time, a keyword, or aphrase, such as “Ah,”, “Um,”, “Hmm,”, “No . . . ”, or the like. Thekeywords and phrases may be populated by a system administrator or anend user and may include both text as well as audio samples. Forinstance, the list of potential interruption inputs may include a textlist of the possible keywords that indicate an appropriate time for amedia guidance application to interrupt or change the subject of aconversation. The list of interruption inputs may also include aplurality of audio samples of a generic male voice and/or a genericfemale voice that speak these keywords or phrases. In some embodiments,the media guidance data source 418 may store audio samples of thespecific end user speaking the interruption keywords and phrases. Theaudio samples may be established, for example, in a setup orinitialization procedure for the media guidance application.

In some embodiments, guidance data from media guidance data source 418may be provided to users' equipment using a client-server approach. Forexample, a user equipment device may pull media guidance data from aserver, or a server may push media guidance data to a user equipmentdevice. In some embodiments, a guidance application client residing onthe user's equipment may initiate sessions with source 418 to obtainguidance data when needed, e.g., when the guidance data is out of dateor when the user equipment device receives a request from the user toreceive data. Media guidance may be provided to the user equipment withany suitable frequency (e.g., continuously, daily, a user-specifiedperiod of time, a system-specified period of time, in response to arequest from user equipment, etc.). Media guidance data source 418 mayprovide user equipment devices 402, 404, and 406 the media guidanceapplication itself or software updates for the media guidanceapplication.

In some embodiments, the media guidance data may include viewer data.For example, the viewer data may include current and/or historical useractivity information (e.g., what content the user typically watches,what times of day the user watches content, whether the user interactswith a social network, at what times the user interacts with a socialnetwork to post information, what types of content the user typicallywatches (e.g., pay TV or free TV), mood, brain activity information,etc.). The media guidance data may also include subscription data. Forexample, the subscription data may identify to which sources or servicesa given user subscribes and/or to which sources or services the givenuser has previously subscribed but later terminated access (e.g.,whether the user subscribes to premium channels, whether the user hasadded a premium level of services, whether the user has increasedInternet speed). In some embodiments, the viewer data and/or thesubscription data may identify patterns of a given user for a period ofmore than one year. The media guidance data may include a model (e.g., asurvivor model) used for generating a score that indicates a likelihooda given user will terminate access to a service/source. For example, themedia guidance application may process the viewer data with thesubscription data using the model to generate a value or score thatindicates a likelihood of whether the given user will terminate accessto a particular service or source. In particular, a higher score mayindicate a higher level of confidence that the user will terminateaccess to a particular service or source. Based on the score, the mediaguidance application may generate promotions and advertisements thatentice the user to keep the particular service or source indicated bythe score as one to which the user will likely terminate access.

Media guidance applications may be, for example, stand-aloneapplications implemented on user equipment devices. For example, themedia guidance application may be implemented as software or a set ofexecutable instructions which may be stored in storage 308, and executedby control circuitry 304 of a user equipment device 300. In someembodiments, media guidance applications may be client-serverapplications where only a client application resides on the userequipment device, and server application resides on a remote server. Forexample, media guidance applications may be implemented partially as aclient application on control circuitry 304 of user equipment device 300and partially on a remote server as a server application (e.g., mediaguidance data source 418) running on control circuitry of the remoteserver. When executed by control circuitry of the remote server (such asmedia guidance data source 418), the media guidance application mayinstruct the control circuitry to generate the guidance applicationdisplays and transmit the generated displays to the user equipmentdevices. The server application may instruct the control circuitry ofthe media guidance data source 418 to transmit data for storage on theuser equipment. The client application may instruct control circuitry ofthe receiving user equipment to generate the guidance applicationdisplays.

Content and/or media guidance data delivered to user equipment devices402, 404, and 406 may be over-the-top (OTT) content. OTT contentdelivery allows Internet-enabled user devices, including any userequipment device described above, to receive content that is transferredover the Internet, including any content described above, in addition tocontent received over cable or satellite connections. OTT content isdelivered via an Internet connection provided by an Internet serviceprovider (ISP), but a third party distributes the content. The ISP maynot be responsible for the viewing abilities, copyrights, orredistribution of the content, and may only transfer IP packets providedby the OTT content provider. Examples of OTT content providers includeYOUTUBE, NETFLIX, and HULU, which provide audio and video via IPpackets. Youtube is a trademark owned by Google Inc., Netflix is atrademark owned by Netflix Inc., and Hulu is a trademark owned by Hulu,LLC. OTT content providers may additionally or alternatively providemedia guidance data described above. In addition to content and/or mediaguidance data, providers of OTT content can distribute media guidanceapplications (e.g., web-based applications or cloud-based applications),or the content can be displayed by media guidance applications stored onthe user equipment device.

Media guidance system 400 is intended to illustrate a number ofapproaches, or network configurations, by which user equipment devicesand sources of content and guidance data may communicate with each otherfor the purpose of accessing content and providing media guidance. Theembodiments described herein may be applied in any one or a subset ofthese approaches, or in a system employing other approaches fordelivering content and providing media guidance. The following fourapproaches provide specific illustrations of the generalized example ofFIG. 4.

In one approach, user equipment devices may communicate with each otherwithin a home network. User equipment devices can communicate with eachother directly via short-range point-to-point communication schemesdescribed above, via indirect paths through a hub or other similardevice provided on a home network, or via communications network 414.Each of the multiple individuals in a single home may operate differentuser equipment devices on the home network. As a result, it may bedesirable for various media guidance information or settings to becommunicated between the different user equipment devices. For example,it may be desirable for users to maintain consistent media guidanceapplication settings on different user equipment devices within a homenetwork, as described in greater detail in Ellis et al., U.S. patentapplication Ser. No. 11/179,410, filed Jul. 11, 2005. Different types ofuser equipment devices in a home network may also communicate with eachother to transmit content. For example, a user may transmit content fromuser computer equipment to a portable video player or portable musicplayer.

In a second approach, users may have multiple types of user equipment bywhich they access content and obtain media guidance. For example, someusers may have home networks that are accessed by in-home and mobiledevices. Users may control in-home devices via a media guidanceapplication implemented on a remote device. For example, users mayaccess an online media guidance application on a website via a personalcomputer at their office, or a mobile device such as a PDA orweb-enabled mobile telephone. The user may set various settings (e.g.,recordings, reminders, or other settings) on the online guidanceapplication to control the user's in-home equipment. The online guidemay control the user's equipment directly, or by communicating with amedia guidance application on the user's in-home equipment. Varioussystems and methods for user equipment devices communicating, where theuser equipment devices are in locations remote from each other, isdiscussed in, for example, Ellis et al., U.S. Pat. No. 8,046,801, issuedOct. 25, 2011, which is hereby incorporated by reference herein in itsentirety.

In a third approach, users of user equipment devices inside and outsidea home can use their media guidance application to communicate directlywith content source 416 to access content. Specifically, within a home,users of user television equipment 402 and user computer equipment 404may access the media guidance application to navigate among and locatedesirable content. Users may also access the media guidance applicationoutside of the home using wireless user communications devices 406 tonavigate among and locate desirable content.

In a fourth approach, user equipment devices may operate in a cloudcomputing environment to access cloud services. In a cloud computingenvironment, various types of computing services for content sharing,storage or distribution (e.g., video sharing sites or social networkingsites) are provided by a collection of network-accessible computing andstorage resources, referred to as “the cloud.” For example, the cloudcan include a collection of server computing devices, which may belocated centrally or at distributed locations, that provide cloud-basedservices to various types of users and devices connected via a networksuch as the Internet via communications network 414. These cloudresources may include one or more content sources 416 and one or moremedia guidance data sources 418. In addition or in the alternative, theremote computing sites may include other user equipment devices, such asuser television equipment 402, user computer equipment 404, and wirelessuser communications device 406. For example, the other user equipmentdevices may provide access to a stored copy of a video or a streamedvideo. In such embodiments, user equipment devices may operate in apeer-to-peer manner without communicating with a central server.

The cloud provides access to services, such as content storage, contentsharing, or social networking services, among other examples, as well asaccess to any content described above, for user equipment devices.Services can be provided in the cloud through cloud computing serviceproviders, or through other providers of online services. For example,the cloud-based services can include a content storage service, acontent sharing site, a social networking site, or other services viawhich user-sourced content is distributed for viewing by others onconnected devices. These cloud-based services may allow a user equipmentdevice to store content to the cloud and to receive content from thecloud rather than storing content locally and accessing locally-storedcontent.

A user may use various content capture devices, such as camcorders,digital cameras with video mode, audio recorders, mobile phones, andhandheld computing devices, to record content. The user can uploadcontent to a content storage service on the cloud either directly, forexample, from user computer equipment 404 or wireless usercommunications device 406 having content capture feature. Alternatively,the user can first transfer the content to a user equipment device, suchas user computer equipment 404. The user equipment device storing thecontent uploads the content to the cloud using a data transmissionservice on communications network 414. In some embodiments, the userequipment device itself is a cloud resource, and other user equipmentdevices can access the content directly from the user equipment deviceon which the user stored the content.

Cloud resources may be accessed by a user equipment device using, forexample, a web browser, a media guidance application, a desktopapplication, a mobile application, and/or any combination of accessapplications of the same. The user equipment device may be a cloudclient that relies on cloud computing for application delivery, or theuser equipment device may have some functionality without access tocloud resources. For example, some applications running on the userequipment device may be cloud applications, i.e., applications deliveredas a service over the Internet, while other applications may be storedand run on the user equipment device. In some embodiments, a user devicemay receive content from multiple cloud resources simultaneously. Forexample, a user device can stream audio from one cloud resource whiledownloading content from a second cloud resource. Or a user device candownload content from multiple cloud resources for more efficientdownloading. In some embodiments, user equipment devices can use cloudresources for processing operations such as the processing operationsperformed by processing circuitry described in relation to FIG. 3.

As referred herein, the term “in response to” refers to initiated as aresult of. For example, a first action being performed in response toanother action may include interstitial steps between the first actionand the second action. As referred herein, the term “directly inresponse to” refers to caused by. For example, a first action beingperformed directly in response to another action may not includeinterstitial steps between the first action and the second action.

The media guidance application may provide media guidance andrecommendation features to the user through a voice interface. Forexample, the media guidance application may hold a conversation with theuser, where the user provides a voice query, the media guidanceapplication provides a spoken answer, and so on. In this manner, themedia guidance application and the user may hold a back-and-forthconversation related to a topic of the user's choice.

In some embodiments, the media guidance application may “interrupt” theuser and/or change the subject of the conversation. For example, theuser may pause or hesitate, and the media guidance application maydetect this pause or hesitation and interject with another spokenresponse. In this manner, the media guidance application is breaking the“turn-based” approach of a traditional voice interface and allowing themedia guidance application to provide several potential answers when theuser indicates hesitation.

The media guidance application may maintain “personalities” that may beselected by the user. The different personalities may utilize differentmodels, as discussed further below, that differ at least in thefrequency with which they interrupt the user and how far the personalitymay stray from a current topic. For example, “Rachael” may be apersonality that employs a female voice, interrupts with a normalfrequency, and rarely strays from a current topic. For instance, if auser asked Rachael for recommendations for science fiction movies,Rachael may respond with “How about Star Trek?”, and after five secondsof silence, may respond with “How about Star Wars?” In contrast, “Rambo”may employ a tough male voice that interrupts with high frequency andinterrupts with wide changes in subject. For example, the user may askRambo for action movie recommendations. In response, Rambo may bombardthe user with rapid-fire suggestions: “HOW ABOUT MISSION IMPOSSIBLE 3??TOO SLOW!! HOW ABOUT INDEPENDENCE DAY??” The user may choose theirpreferred personality to interact with, or even create their own custompersonality.

FIG. 5 is a flowchart 500 of illustrative steps for control circuitry(such as control circuitry 304) to provide media guidance in accordancewith some embodiments of the disclosure. Flowchart 500 describes controlcircuitry 304 receiving a first voice input, providing a first response,detecting an interruption point, and providing a second response that isrelated to a topic of the first voice input. In some embodiments, thisprocess may be encoded on to non-transitory storage medium (such asstorage device 308) as a set of instructions to be decoded and executedby processing circuitry (such as processing circuitry 306). Processingcircuitry may in turn provide instructions to other sub-circuitscontained within control circuitry 304, such as the tuning, videogenerating, encoding, decoding, encrypting, decrypting, scaling,analog/digital conversion circuitry, image recognition and analysiscircuitry, and the like.

At 502, the process to provide media guidance may begin. In someembodiments, the process may begin either directly or indirectly inresponse to a request from the user or a user action, such as an inputinto user input interface 310. For example, the process may begindirectly in response to control circuitry 304 receiving signals fromuser input interface 310 or control circuitry 304 may prompt the user toconfirm their input using a display (such as display 312) prior torunning the process.

At 504, the control circuitry 304 may receive a first voice input. Insome embodiments, the control circuitry 304 may receive the first voiceinput using audio recognition hardware, such as detection module 316. Insome embodiments, the control circuitry 304 may also run audiorecognition software in order to recognize the first voice input. At506, the control circuitry 304 may access a database of topics, thedatabase of topics including a semantic network indicating relationshipsbetween a plurality of topics. As discussed above, the semantic networkmay be populated in any suitable method and may indicate relationshipsin any suitable manner. In some embodiments, the semantic network may bea knowledge graph that represents topics as nodes/vertices in a directedor undirected graph and relationships as numerical values indicating thesimilarity or dissimilarity between topics.

At 508, the control circuitry 304 may identify a first topic from thedatabase of topics that is associated with the first voice input. Thecontrol circuitry 304 may identify the first topic in any suitablemanner. In some embodiments, as discussed below in relation to FIG. 8,the control circuitry 304 may use audio recognition software to extractkeywords from the first voice input. The control circuitry 304 maycompare these extracted keywords to keywords of topics associated withthe first topic. For example, the database of topics may maintain, foreach topic, a list of keywords associated with the topic. In someembodiments, the keywords themselves may be indicated as separatevertices/nodes in the database of topics. The control circuitry 304 mayidentify a subset of topics and select, of the subset of topics, onetopic that represents the closest match. For instance, the matchingtopic may represent the topic of the subset of topics that matches themost number of keywords extracted from the first voice input.

At 510, a user interface may generate a first response to the firstvoice input. The user interface may include speakers to output a voiceresponse and/or a display for relaying text-based answers. The firstresponse may be determined in any suitable manner. For example, asdiscussed below in relation to FIG. 9, the first response may bedetermined by identifying a topic related to the topic of the firstvoice input. As an illustrative example, the user may query, “Pleaserecommend a popular sci-fi movie.” The system may identify “sciencefiction” as the topic of the user's voice input, and may identify “StarTrek” as a topic related to “science fiction.” After identifying thetopic, the system may incorporate the related topic into a suitableresponse to the user's query. For example, the media guidanceapplication may respond with “How about the Star Trek movie from 2009?”At 512, subsequent to generating the first response, the controlcircuitry 304 may receive a second voice input. 512 may be substantiallysimilar to 504. For instance, the control circuitry 304 may receive thesecond voice input using audio recognition hardware, such as detectionmodule 316. In some embodiments, the control circuitry 304 may also runaudio recognition software in order to recognize the second voice input.

At 514, the control circuitry 304 may monitor the second voice input todetermine whether it includes an interruption input, indicating that itmay be an appropriate time for the media guidance application tointerject with a change of subject. To this end, the control circuitry304 may compare the second voice input to a list of interruption inputsto determine a match between the second voice input and an interruptioninput from the list of interruption inputs. The control circuitry 304may retrieve the list of interruption inputs from any suitable storage,such as local storage 308 or remote storage, such as media guidance datasource 418. The control circuitry 304 may extract one or more keywordsfrom the second voice input. For example, the control circuitry 304 mayutilize audio recognition software to convert the second voice inputinto text and parse the text into keywords or phrases. The controlcircuitry 304 may then compare the extracted keywords to theinterruption inputs from the list of interruption inputs. In someembodiments, the comparison includes a text-to-text search of theextracted keywords and the text of the interruption inputs. Any othersuitable comparison is contemplated, including audio-to-text,text-to-audio, and audio-to-audio comparisons. For example, the list ofinterruption inputs may include both a text representation of thekeyword as well as one or more associated audio samples of a humanspeaking the keyword. The control circuitry 304 may perform a directaudio comparison between the second voice input and the audio samples inthe list of interruption inputs in order to identify a match.

At 516, the control circuitry 304 may, in response to determining amatch between the second voice input and the interruption input,generate a second response to the first voice input. In someembodiments, the second response to the first voice input may bedetermined in much the same way as the first response from 510. Thesecond response may be associated with a second topic from the databaseof topics that is associated with the first topic. The control circuitry304 may access the database of topics and identify a subset of topicsthat are within a relationship threshold of the first topic of the firstvoice input. The control circuitry 304 may select one topic from thesubset of topics and form a response based on the topic, as discussedabove in relation to 510 and below in relation with FIG. 12.

FIG. 6 is a flowchart 600 of illustrative steps for receiving a firstvoice input. Flowchart 600 describes that steps that control circuitry304 would take to receive and store the first voice input to memory. At602, the process to receive a first voice input may begin. In someembodiments, the process may begin either directly or indirectly inresponse to a request from the user or a user action, such as an inputinto user input interface 310. For example, the process may begindirectly in response to control circuitry 304 receiving signals fromuser input interface 310 or control circuitry 304 may prompt the user toconfirm their input using a display (such as display 312) prior torunning the process. In some embodiments, the control circuitry 304 mayping either local storage 308 or remote storage, such as media guidancedata source 418, to determine whether the storage is available and readyto store the first voice input. The control circuitry 304 may alsoinitialize any variables necessary to store the first voice input. Forexample, the control circuitry 304 may initialize an array in memory tostore audio signals for successive time periods. In some embodiments,the control circuitry 304 may allocate a one-dimensional variable tocontinuously store a stream of audio.

At 604, the control circuitry may activate the voice detection module,such as detection module 316. For example, the voice detection modulemay include a microphone or any other audio detection hardware suitablefor detecting and recording audio signals. At 606, the control circuitry304 may monitor an audio signal using the voice detection module. Forexample, the control circuitry 304 may receive the audio signal usingthe voice detection module and store and/or continuously stream theaudio signal to memory. At 608, the control circuitry 304 may establisha baseline signal. For instance, the control circuitry 304 may monitor acertain period of time of silence and/or background noise. As will beunderstood by those of skill in the art, suitable audio analytics,including performing low/high/band-pass filtering and/or transformanalysis may be performed in order to identify and isolate the baselinesignal.

At 610, the control circuitry 304 may detect, at a start time, adeviation above threshold value of monitored audio signal from baselinesignal. For instance, the threshold value may include a thresholddecibel level above silence, and the control circuitry 304 may detectthat the monitored audio signal has exceeded that threshold decibellevel, thus indicating the start of a voice input. In some embodiments,the control circuitry 304 may first remove the baseline signal usingaudio analysis techniques, as will be understood by those of skill inthe art. As an illustrative example, the control circuitry 304 maydevelop a signature frequency profile of the baseline signal,representing the background noise. The control circuitry 304 may removethis signature frequency profile from a currently detected audio signalin order to remove the background noise, and may then detect whether theresulting audio signal exceeds a threshold value.

At 612, the control circuitry 304 may detect, at an end time, that themonitored audio signal has returned to within a threshold value of thebaseline signal. For example, similar to 610 discussed above, thethreshold value may be a threshold decibel level, and the controlcircuitry 304 may detect when the monitored audio signal drops below thethreshold decibel level. As discussed above in 610, the controlcircuitry 304 may first remove a signature frequency profile ofbackground noise from the monitored audio signal before determiningwhether the signal has dropped below the threshold value. In someembodiments, the control circuitry 304 detects whether there has beensilence for a predetermined amount of time. For example, a period ofsilence of is may indicate that the user has finished his or her queryto the media guidance application. At 614, the control circuitry 304 mayidentify a portion of the monitored audio signal between the start timeand the end time as the first voice input and store the first voiceinput to memory at 616.

FIG. 7 is a flowchart 700 of illustrative steps for accessing a databaseof topics. Flowchart 700 describes the steps that control circuitry 304may take to access the database of topics. Control circuitry 304 mayaccess the database of topics using any suitable method, and flowchart700 is provided as an illustrative example only. For instance, asdiscussed above and throughout, the database of topics may include asemantic network such as a Knowledge Graph and may be stored either inlocal storage, such as storage 308, or in remote storage, such as mediaguidance data source 418. If the database of topics is stored in localstorage 308, the control circuitry 304 may access the database throughinternal memory channels of the user equipment device 300. If thedatabase of topics is stored in remote storage, such as media guidancedata source 418, the control circuitry 304 may access the databasethrough, for example, communications network 414, including, but notlimited to, local area networks (LAN), the Internet, or a combination ofthe two.

At 702, the control circuitry may begin a process to access the databaseof topics, including any appropriate initialization and allocationroutines. At 704, the control circuitry 304 may transmit a ping to thedatabase of topics over a network. As discussed above, the network mayinclude any type of network, including a local network, the Internet, orlocal memory channels. The ping may include a short data message thatqueries whether the database is ready to accept commands and/or data. At706, the control circuitry 304 may receive a response to the ping fromthe database of topics, indicating that the database of topics is readyto receive a query. As with the ping, the response may be a short datamessage that indicates that the database is ready to accept commandsand/or data.

FIG. 8 is a flowchart 800 of illustrative steps for identifying a firsttopic that is associated with the first voice input. FIG. 8 describes aniterative process in which each of the topics in the database of topicsis compared to the first voice input in order to determine the closestmatching topic. At 802, the process to identify a first topic that isassociated with the first voice input may begin. In some embodiments,the process may begin either directly or indirectly in response to arequest from the user or a user action, such as an input into user inputinterface 310. For example, the process may begin directly in responseto control circuitry 304 receiving signals from user input interface 310or control circuitry 304 may prompt the user to confirm their inputusing a display (such as display 312) prior to running the process.

At 804, the control circuitry may extract one or more keywords from thefirst voice input. In some embodiments, extracting keywords from thefirst voice input may include converting the audio signal of the firstvoice input into a text format using suitable audio recognitionsoftware. The converted text may be parsed or grouped into suitablekeywords and/or phrases. In some embodiments, the keywords may beextracted as audio samples of the first voice input. The controlcircuitry 304 may use suitable audio recognition software to separatethe individual words and/or phrases spoken by the user in the firstvoice input. For instance, the control circuitry 304 may detect briefpauses or periods of silence in the first voice input to delineate wordsor phrases.

At 806, the control circuitry 304 may optionally transmit the extractedkeywords to the database of topics, for example via network 414. In suchembodiments, the control circuitry 304 may query the database of topicsto identify the first topic, and the database of topics may perform thesubsequent steps 808 to 816 and return the result to the controlcircuitry 304 via network 414.

At 808, the control circuitry 304 may select a topic from the databaseof topics, and at 810, determine whether the selected topic matches anextracted keyword(s). In some embodiments, the database of topics maylist several keywords associated with the selected topic. Theseassociated keywords may be compared to the extracted keywords using anysuitable method, including a text-to-text comparison, text-to-audiocomparison, audio-to-text comparison, or audio-to-audio comparison. Ifnone of the extracted keywords match the keywords associated with theselected topic, then the control circuitry 304 may return to 808. If oneor more keywords match, then the control circuitry may continue to 812.

At 812, the control circuitry 304 may determine whether the currentlyselected topic is the closest matching topic in the database of topicsto the first voice input. To this end, the control circuitry 304 maydetermine either (1) no topic is currently stored to memory as amatching topic; or (2) the currently selected topic contains morematching keywords than the currently stored matching topic. If thecontrol circuitry 304 determines that neither (1) nor (2) is true, thenthe control circuitry 304 may return to 808. If the control circuitry304 determines that either (1), (2), or both are true, then the controlcircuitry 304 may continue to 814 and store the selected topic to memoryas the current closest matching topic. At 816, the control circuitry 816may determine whether there are any remaining topics in the database oftopics to compare to the extracted keywords. If there are topicsremaining, then the control circuitry 304 may return to 808 and select adifferent topic from the database of topics. If all topics have beencompared against the extracted keywords, then the control circuitry 304may, at 818, return the topic stored to memory as the result of theprocess. In this manner, the topic from the database of topics that mostclosely matches the keywords extracted from the first voice input isreturned as the topic of the first voice input. As will be understood bythose of skill in the art, FIG. 8 is provided for illustrative purposesonly, and other methods for identifying a first topic of the first voiceinput may be utilized, as will be understood by those of ordinary skillin the art.

FIG. 9 is a flowchart 900 of illustrative steps for generating a firstresponse to the first voice input. FIG. 9 describes the steps thatcontrol circuitry 304 may take to output a first response to the user'sfirst voice input. At 902, the process to generating a first response tothe first voice input may begin. In some embodiments, the process maybegin either directly or indirectly in response to a request from theuser or a user action, such as an input into user input interface 310.For example, the process may begin directly in response to controlcircuitry 304 receiving signals from user input interface 310 or controlcircuitry 304 may prompt the user to confirm their input using a display(such as display 312) prior to running the process.

At 904, the control circuitry 904 may access the database of topics. 904may be substantially similar to 506 and/or process 700, as discussedabove in relation to FIGS. 5 and 7, respectively. At 906, the controlcircuitry 304 may extract, from the database, relationships between thefirst topic and a remainder of the plurality of topics. As discussedabove, the relationships may be kept in any suitable manner. Forexample, the relationships may be represented by numerical valuesbetween nodes of a Knowledge Graph. At 908, the control circuitry 904may access a voice personality profile to retrieve a relationshipthreshold. As discussed above, the relationship threshold may be ametric that may be used to determine whether a first topic is related toa second topic. The voice personality profile may be stored either onlocal storage, such as storage 308 or remote storage, such as mediaguidance data source 418.

At 910, the control circuitry 304 may compare each of the relationshipsbetween the first topic and the remainder of topics to the relationshipthreshold. For example, in some embodiments, the comparison may includedetermining whether a numerical value of a particular relationship isgreater than a numerical relationship threshold. At 912, the controlcircuitry may identify, based on the comparison, a subset of therelationships that do not exceed the relationship threshold and a listof topics that corresponds to the subset of relationships. These listsmay represent the list of topics that are related to the first topics ofthe first voice input.

At 914, the control circuitry may select one of the topics from the listof topics. The control circuitry 304 may select the topic in anysuitable manner. For example, the control circuitry may select the topicthat is the closest match to the first topic, similar to 812 discussedabove in relation to FIG. 8. In some embodiments, the control circuitrymay incorporate a user's media preferences in the selection of a topicfrom the list of topics. For example, the control circuitry 304 mayaccess a user profile, for instance stored on local storage 308, andextract one or more media preferences from the user profile. As anillustrative example, the control circuitry 304 may extract a genrepreference of the user from the user profile. The control circuitry 304may then further filter the subset of topics to those that satisfy themedia preference of the user. Extending the illustrative example above,the control circuitry 304 may select only those topics that both relateto the first topic of the first voice input and that relates to a genrethat is preferred by the user. In some embodiments, where a plurality oftopics remains after all selection criteria have been applied, thecontrol circuitry 304 may select one of the remaining topics at random.As will be understood by one of ordinary skill in the art, theseexamples are provided for illustrative purposes only, and the controlcircuitry 304 may select one of the topics using any suitable means.

At 916, the control circuitry 304 may output on a user interface a firstresponse based on the selected topic. In some embodiments, 916 includesgenerating a full sentence based on the selected topic. In someembodiments, the control circuitry 304 may access a list of responsesthat have been previously authored by a human, wherein each of the listof responses leaves a blank to insert a relevant keyword. In suchinstances, the control circuitry 304 may access a list of keywordsassociated with the selected topic, select one of the responses from thelist of responses, and input a keyword into the blank in order tocompose the full sentence. As an illustrative example, the controlcircuitry 304 may select “How about _(——————)?” as a potential response,and identify “Star Trek” as the selected topic. The control circuitry304 may insert the key phrase “Star Trek” into the blank to compose thefull sentence “How about Star Trek?” As will be understood by those ofordinary skill in the art, these examples are provided for illustrativepurposes only, and other methods of outputting the first response may becontemplated.

FIG. 10 is a flowchart 1000 of illustrative steps for receiving a secondvoice input subsequent to generating the first response. Flowchart 1000describes the steps that a control circuitry may take to receive andstore a second voice input to memory. The steps of FIG. 10 may besubstantially similar to the steps discussed above in relation to FIG.6. At 1002, the process to receive a second voice input may begin. Insome embodiments, the process may begin either directly or indirectly inresponse to a request from the user or a user action, such as an inputinto user input interface 310. For example, the process may begindirectly in response to control circuitry 304 receiving signals fromuser input interface 310 or control circuitry 304 may prompt the user toconfirm their input using a display (such as display 312) prior torunning the process. In some embodiments, the control circuitry 304 mayping either local storage 308 or remote storage, such as media guidancedata source 418, to determine whether the storage is available and readyto store the second voice input. The control circuitry 304 may alsoinitialize any variables necessary to store the second voice input. Forexample, the control circuitry 304 may initialize an array in memory tostore audio signals for successive time periods. In some embodiments,the control circuitry 304 may allocate a one-dimensional variable tocontinuously store a stream of audio.

At 1004, the control circuitry 304 may activate the voice detectionmodule, such as detection module 316. For example, the voice detectionmodule may include a microphone or any other audio detection hardwaresuitable for detecting and recording audio signals. At 1006, the controlcircuitry 304 may monitor an audio signal using the voice detectionmodule. For example, the control circuitry 304 may receive the audiosignal using the voice detection module and store and/or continuouslystream the audio signal to memory. In some embodiments, the controlcircuitry 304 may continuously record audio from the second voice inputto the second voice input. At 1008, the control circuitry 304 mayestablish a baseline signal. For instance, the control circuitry 304 maymonitor a certain period of time of silence and/or background noise. Aswill be understood by those of skill in the art, suitable audioanalytics, including performing low/high/band-pass filtering and/ortransform analysis may be performed in order to identify and isolate thebaseline signal.

At 1010, the control circuitry 304 may detect, at a start time, adeviation above threshold value of monitored audio signal from baselinesignal. For instance, the threshold value may include a thresholddecibel level above silence, and the control circuitry 304 may detectthat the monitored audio signal has exceeded that threshold decibellevel, thus indicating the start of a voice input. In some embodiments,the control circuitry 304 may first remove the baseline signal usingaudio analysis techniques, as will be understood by those of skill inthe art. As an illustrative example, the control circuitry 304 maydevelop a signature frequency profile of the baseline signal,representing the background noise. The control circuitry 304 may removethis signature frequency profile from a currently detected audio signalin order to remove the background noise, and may then detect whether theresulting audio signal exceeds a threshold value.

At 1012, the control circuitry 304 may detect, at an end time, that themonitored audio signal has returned to within a threshold value of thebaseline signal. For example, similar to 1010 discussed above, thethreshold value may be a threshold decibel level, and the controlcircuitry 304 may detect when the monitored audio signal drops below thethreshold decibel level. As discussed above in 1010, the controlcircuitry 304 may first remove a signature frequency profile ofbackground noise from the monitored audio signal before determiningwhether the signal has dropped below the threshold value. In someembodiments, the control circuitry 304 detects whether there has beensilence for a predetermined amount of time. For example, a period ofsilence of is may indicate that the user has finished his or her queryto the media guidance application. At 1014, the control circuitry 304may identify a portion of the monitored audio signal between the starttime and the end time as the second voice input and store the secondvoice input to memory at 1016.

FIG. 11 is a flowchart 1100 of illustrative steps for comparing thesecond voice input to identify an interruption input. Flowchart 1100describes the process by which control circuitry 304 may compare thesecond voice input to a list of interruption inputs in order to identifywhether the second voice input includes an appropriate interruptioninput. At 1102, the process to compare the second voice input toidentify an interruption input may begin. In some embodiments, theprocess may begin either directly or indirectly in response to a requestfrom the user or a user action, such as an input into user inputinterface 310. For example, the process may begin directly in responseto control circuitry 304 receiving signals from user input interface 310or control circuitry 304 may prompt the user to confirm their inputusing a display (such as display 312) prior to running the process.

At 1104, the control circuitry 304 may access a database and retrieve alist of interruption inputs. In some embodiments the database storingthe list of interruption inputs may be the same database as the databaseof topics. In some embodiments the database storing the list ofinterruption inputs may be a different database as the database oftopics. The database storing the list of interruption inputs may bestored in any suitable storage, including local storage 308 and remotestorage, such as media guidance data source 418.

At 1106, the control circuitry 304 may extract keyword(s) from thesecond voice input. 1106 may be substantially similar to 804 discussedabove in relation to FIG. 8. In some embodiments, extracting keywordsfrom the second voice input may include converting the audio signal ofthe second voice input into a text format using suitable audiorecognition software. The converted text may be parsed or grouped intosuitable keywords and/or phrases. In some embodiments, the keywords maybe extracted as audio samples of the second voice input. The controlcircuitry 304 may use suitable audio recognition software to separatethe individual words and/or phrases spoken by the user in the secondvoice input. For instance, the control circuitry 304 may detect briefpauses or periods of silence in the second voice input to delineatewords or phrases.

At 1108, the control circuitry 304 may select an interruption input fromthe list of interruption input. At 1110, the control circuitry 304 maycompare the selected interruption input to the extracted keyword(s) todetermine whether there is a match. 1110 may be substantially similar to810 discussed above in relation to FIG. 8. For instance, the selectedinterruption input may be compared to the extracted keywords in anysuitable manner, including a text-to-text comparison, text-to-audiocomparison, audio-to-text comparison, or audio-to-audio comparison. Ifnone of the extracted keywords match the selected interruption input,then the control circuitry 304 may return to 1108. If one or morekeywords match, then the control circuitry may continue to 1112 andreturn an indication of a match between the second voice input and theinterruption input.

FIG. 12 is a flowchart 1200 of another set of illustrative steps forgenerating a second response to the first voice input. FIG. 12 describesthe process by which a control circuitry 304 may change the subject,including how to integrate user preferences into the response and whento wait for an appropriate time to respond. At 1202, the process togenerate a second response to the first voice input may begin. In someembodiments, the process may begin either directly or indirectly inresponse to a request from the user or a user action, such as an inputinto user input interface 310. For example, the process may begindirectly in response to control circuitry 304 receiving signals fromuser input interface 310 or control circuitry 304 may prompt the user toconfirm their input using a display (such as display 312) prior torunning the process.

1204 to 1212 of FIG. 12 may be substantially similar to 904 to 912 ofFIG. 9, discussed above. At 1208, the control circuitry 304 may furtherretrieve an interruption threshold period of time from the voicepersonality profile. At 1214, the control circuitry 304 may determinewhether to integrate user preferences to the generated response. Forexample, the control circuitry 304 may identify whether an option tointegrate user preferences into the media guidance application's voiceresponses has been selected by the user. If the user preferences are notto be integrated into the response, then the control circuitry maycontinue to 1220 and select a topic from the list of topics. 1220 may besubstantially similar to 914 discussed above in relation to FIG. 9. Ifthe user preferences are to be integrated into the response, then thecontrol circuitry 304 may retrieve a genre preference from the userprofile at 1216. At 1218, the control circuitry 304 may select a topicfrom the list of topics that relates to the genre preference. Forinstance, the control circuitry 304 may filter the subset of topicsbased on the genre preference and select one of the resulting topics. At1222, the control circuitry 304 may compare a current time to a timeassociated with the first voice input in order to calculate a timeelapsed. For example, the control circuitry 304 may access the currenttime from a clock or other timekeeping hardware and may retrieve thetime associated with the first voice input, such as a timestamp, fromstorage, such as local storage 308. The control circuitry may take adifference of the current time and the time associated with the firstvoice input to calculate the time elapsed.

At 1224, the control circuitry 304 may determine whether the timeelapsed exceeds the interruption threshold period of time. If the timeelapsed does not exceed the interruption threshold period of time, thenthe control circuitry 304 may return to 1222 until the time elapsed doesexceed the threshold period of time. This may occur in a situation wherethe user does not wish to be interrupted with frequency greater than theinterruption threshold period of time. If the time elapsed exceeds theinterruption threshold period of time, then the control circuitry 304may continue to 1226 and output, using the user interface, a secondresponse based on the selected topic. 1226 may be substantially similarto 916 described above in relation to FIG. 9. In some embodiments, 1226includes generating a full sentence based on the selected topic. In someembodiments, the control circuitry 304 may access a list of responsesthat have been previously authored by a human, wherein each of the listof responses leaves a blank to insert a relevant keyword. In suchinstances, the control circuitry 304 may access a list of keywordsassociated with the selected topic, select one of the responses from thelist of responses, and input a keyword into the blank in order tocompose the full sentence.

The above-described embodiments of the present disclosure are presentedfor purposes of illustration and not of limitation, and the presentdisclosure is limited only by the claims that follow. Furthermore, itshould be noted that the features and limitations described in any oneembodiment may be applied to any other embodiment herein, and flowchartsor examples relating to one embodiment may be combined with any otherembodiment in a suitable manner, done in different orders, or done inparallel. In addition, the systems and methods described herein may beperformed in real time. It should also be noted that the systems and/ormethods described above may be applied to, or used in accordance with,other systems and/or methods.
